ClampSet "Mode" to "Clamp" could clamp the position of object in the boundary.

Set "Align" to "Boundaries" could clamp the object according to the boundaries of this object, or

Set "Align" to "Origin", to clamp this object according to origin point (i.e. instance's XY position) of this object.

WrapSet "Mode" to "Wrap". The object which has left out one boundary, will be reappear at the other side.

Set "Align" to "Boundaries" will do wrapping until whole object has left out the boundary. This behavior is similar with official wrap behavior.

Set "Align" to "Origin" will do wrapping when the origin point of this object has left out the boundary

Mode wrapSample capxSet "Mode" to "Mod wrap". The object which has left out one boundary, will be reappear at the other side, with an offset to keep the moving distance.For example, if this instance moved out of left bound with offset to -10 pixels, i.e. (left - 10), it would be wrapped to right bound with offset to -10 pixels, i.e. (right - 10).Property "Align" of this mode only supports "Origin".

PercentageUser could get a value between 0 to 1 mapped from left boundary to right boundary, or top boundary to bottom boundary by "Expression:HorPercent" (left-right) , or "Expression:VerPercent" (top-bottom). "Expression:HorScale" and "Expression:VerScale" are advance expressions, they will map the percentage value to another value.This feature might be useful while making a value input interface by scrolling, like the sample capx.

Get position by percentage of boundariesSample capxGet position X/Y from percentage (0-1) of horizontal / vertical boundaries by "Expression:HorPercent2PosX" / "Expression:HorPercent2PosY".
